​Sadly, but there is no 100% working solutions. Hope someday IPS will make their own solution for WP integration. It's the only way when it can be stable. But at this moment there is endless cycle of the emergence and death of third-party WP-integration-solutions. I prefer to pay to IPS rather than get solutions from unknown sources without guaranteed long-term support. So, IPS, guys, do it for us? Hundreds of users and potential clients requesting it for a years. We're really tired of low-quality/unsupported third-party plugins. Give us a solution, we could pay for that

In my opinion this option should be enabled by default, it will help to prevent overuse of formatting by inexperienced users( big rainbow effect ) who even don't know how to paste clean text. Also, in my experience pasting of plain text is more often need than pasting of formated text. What do you think guys? Should be this option enabled by default, or at least should forum admins have option to choose the default state?

Rikki , Charles , yes, i understand that messages like "xyz is completely useless" is not helpful. But I did not want to go into details because this topic is dedicated to private messages, not to ip.chat. I could write a more detailed and constructive review of IP.chat problems, but inappropriate in this topic.
